Toxic Man is one of the eight upcoming Robot Masters in Mega Man Y+1. He along with Timber Man and Volt Man appear in the demo.
Backstory[]
Toxic Man was built to transport and help dispose of toxic waste at a chemical treatment facility. His body and components are coated in special materials which are resistant to the toxins he transports. Due to the nature of his job, he is not allowed outside of the plant, so he knows little about the world outside.
After malfunctioning, Toxic Man has caused dangerous chemicals to leak out of the treatment plant into the city’s water supply.
